Ttoms the baseline'll be lower, so-make a correct match you should know where is the baselines of each word exactly Located. So we need to know the Ascent value of the text. If the got the ascent value, we can easily align the words on the baseline as seen on following image. For a complete information on typography see this article on Wikipedia.For a proper drawing of words in different sizes, should align them on their baselines.As seen on the above image, have the information of the ascent v
Introduction: Software metrics can help you look for hidden design elements in your code so they can become idiomatic patterns. This phase of evolutionary architecture and emergency design explains how to use metrics and visualization to discover important code elements that are masked by complexity.
One of the challenges of emergent design is finding idiomatic patterns and other design elements that are h

The following is a brief list of common recommended system metrics:
1. Accuracy rate and Recall rate (Precision Recall)
Accuracy and recall rates are two measures widely used in the field of information retrieval and statistical classification to evaluate the quality of the results. The accuracy is to retrieve the number of related documents and the total number of documents retrieved, to measure the precision of the retrieval system; Recall is t

My team has popularized the use of Codeanalyzer to analyze Code metrics (metric), sharing experience here.

Article, where the information may have evolved or changed.
Since go 1.5, every go release, Gopher Brian Hatfield has been basking on Twitter for the performance data of the new Go runtime (compared to previous go versions). Even when the Go team staff do speaking around the world, Brian's pictures are also quoted in slide. Later, Brian Hatfield packaged its code for measuring Runtime performance data into a library and put it on GitHub, and we could use the library to buil
1. Overview of completeness metrics
The runtime's system integrity is guaranteed by the system's access control mechanisms, such as DAC (Discrete access control, indirect access controls)/mac (Mandatory access control, mandatory access controls, such as SELinux, Smack).
DAC/MAC cannot detect offline modification of files, Encrypting File System can protect illegal access, but it is expensive and relatively inefficient.
Integrity measu
Starting with VS2008, there is a new tool to help developers better understand the code they write. This tool is "calculated code metrics."
For a specific description of this feature and several indicators, please refer to the official documentation below
